GUI shows incorrect number of members of pool in high availability (HA) group after pool config is sync'ed from peer unit.


The number of pool members listed in the HA Groups page is incorrect (e.g., shows 2 when it should show 1, 3 when it should show 2). Although this issue is cosmetic, it makes it difficult to configure the HA Group on the affected device.


This is triggered when automatic sync is configured with incremental synchronization on a sync-failover device group. It will be visible on the HA Groups page in the Pools section after a configuration sync is performed from a device where the pool members were modified.


The incorrect pool member display can be fixed on the affected device, by running the following tmsh command: Impact of procedure: This command loads the saved configuration, so any in-memory changes (i.e., changes that have not been saved to disk) will be lost. Since the affected device is a sync target, and no other changes should have been made, it should be safe to run this command. tmsh load sys config Running the above workaround may result in the sync status changing from "Sync" to "Changes Pending".

Fix Information

High availability (HA) Groups page now displays the expected pool members on the sync target device after an automatic incremental sync is performed. Note: This issue was erroneously reported as fixed in 11.5.0 documentation. The issue subsequently was found to occur in 11.5.0, its recurrence the result of a different issue. It no longer occurs beginning with version 11.5.4.
